You need to include the path to msaccess.exe, not just the mdb and /x
switch.
The switch is actually for the executable, not the database. Unless you've
modified the default file association, switches get ignored when all you
have is the file in the shortcut.
Don't forget to put quotes around the full path to msaccess.exe, since it's
almost certainly going to have spaces in it (C:\Program Files\....)
